Abstract

Изобретение раскрывает способ обработки подземного пласта в стволе буровой скважины, включающий стадии, в которых создают обрабатывающую текучую среду, приготовленную из текучей среды; дисперсного материала и загущающего материала; причем загущающий материал является неактивным в первом состоянии и способен повышать вязкость обрабатывающей текучей среды, будучи во втором состоянии; вводят обрабатывающую текучую среду в ствол буровой скважины и создают инициатор, способный активировать загущающий материал, переводя его из первого состояния во второе состояние.
